The location of the candles on the VAZ 2114. How often do you need to change the spark plugs on the VAZ. Spark plug replacement interval

2114 and VAZ 2115 are an important element of the ignition system, on which the successful start of the internal combustion engine depends. The article discusses cases when it is necessary to change spark plugs (SZ), which spark plugs to put in, and also provides instructions for replacing them with VAZ 2114 and 2115.

[ Hide ]

In what cases is it necessary to replace spark plugs?

Replacement of SZ with VAZ 2115 and VAZ 214 is carried out every 30,000 thousand kilometers. If you do not change the SZ in time and continue to operate the car, then the wear of the electrodes increases sharply, this entails a drop in the power of the car and excessive fuel consumption. It is possible to determine the condition of the candle and the ignition system as a whole based on the appearance of the electrode, by the amount and color of soot on it. Brown soot is considered normal.

With long-term operation, the characteristics of the motor change. If you carefully follow ICE operation, then, based on fuel consumption, conclusions can be drawn about the state of the SZ. Knowledgeable people recommend changing candles on VAZs after 20 thousand kilometers, and in winter even after 15 thousand.

You can judge the need to replace the SZ by their appearance, more precisely in terms of the amount and color of carbon deposits, as well as the gap between the electrodes.

In addition, the dryness of the thread should be checked. If there are traces of oil on it, this indicates problems with the tightness of the system.

Summing up, we can give cases when it is necessary to change the SZ:

  • the car does not start well;
  • increased fuel consumption;
  • the engine starts to troit;
  • motor power drops;
  • exceeding the recommended mileage for replacement.

What kind of candles to put?

The choice of candles is a responsible matter. The service life of the engine, its power, fuel consumption, and successful launch depend on their quality.

When choosing, the greatest attention should be paid to the central electrode, such indicators as: heat resistance, thermal conductivity and plasticity.

The best products are candles, in which the smallest gap is 0.4-0.8 mm, made of expensive materials: platinum, iridium, palladium coated with silver or gold (video author - Avtosferaomsk).

It is important to understand what candles are produced for the VAZ 2114. When choosing a new product, you need to study its characteristics in order to choose,. A large number of SZ manufacturers have appeared on the car market, but there are several leaders whose products are in the greatest demand. SZ must work synchronously, so you need to buy them from the same manufacturer and from the same material.

Of the domestic manufacturers, one can name those produced in the city of Engels. They are installed on VAZs from the factory. The quality of the products corresponds to the price, but there is a marriage, so when buying they need to be checked for serviceability. Products A-17DVRM (1.0) are produced for engines with an injector 8 and A-17DVRM (1.0) - for 16 valves.


From imported products, good Czech ones. They are in demand due to good quality. There are 10 series of these products, which differ in design. They have a gap of 1.1, there are SZ for 8 valve injection engines - BRISK SUPER FORTE LOR15YC-1 and for 16 valve BRISK SUPER FORTE DOR15YC-1.

Japanese products are always of high quality. These candles are installed on some brands of cars directly at the factory. They have a higher price, but they also have the corresponding quality. When buying, you should beware of fakes, as there are a lot of them. For engines with 8 valves with an injector, DENSO W20TT is suitable, for engines with 16 valves, DENSO W20EPR-U11.

NGK is a leading manufacturer of SZ. They are installed by manufacturers on some brands of foreign cars. A car enthusiast claims that candles serve an average of 25-30 thousand kilometers. For engines with an injector, 16 valves are available spark plugs No. 13 BPR6ES-11.

DIY replacement instructions

Replacing candles with VAZ 2114 and 2115 is not a difficult process. This work can be performed by any motorist, guided by step by step instructions below.

Tools and materials

For the procedure, you must prepare:

  • key to remove protection;
  • a set of round probes;
  • candle key;
  • new set of SZ.

To avoid counterfeiting, you should purchase original products.

The process of dismantling and replacing SZ


The procedure for removing and replacing spark plugs must be carried out on a cold engine to avoid burns.

The process itself consists of the following steps:

  1. First you need to open the hood. Then you need to dismantle the protection from the engine, if present.
  2. After removing the decorative trim, you need to remove the protective caps from which are put on the contacts. Remove the caps carefully so as not to damage the wiring.
  3. Places near the NW should be cleaned of dirt so that they do not get into the engine cylinders.
  4. Now, using a candle key, you need to unscrew the SZ from the cylinder head. You can start twisting from any side. First you need to get off the ground, and then you can carefully unscrew the SZ from the socket.
  5. Having unscrewed the old SZ, you need to wipe the thread with a rag.
  6. Before screwing in new products, it is advisable to check the clearance on each of them. For vehicles with an injector, it should be between 1 and 1.13 mm.
  7. Installing SZ - the same simple procedure as unscrewing, is carried out in the reverse order. New products put on seats old candles. It must be screwed in carefully so as not to damage the threads in the cylinder head or on the product.
  8. Next, you need to put on the tips of high-voltage wires. In this case, you need to make sure that the wire numbers that are marked on them correspond.
  9. At the final stage, the decorative overlay returns to its place.

After replacing the SZ, it is necessary to observe how the engine works. If it works intermittently, it is possible that one of the SZs is defective. To detect it, you need to sequentially turn off each high-voltage wire. A defective spark plug must be replaced.

Replacing spark plugs is a regulated operation. They must be replaced every 15 thousand kilometers. This is due to the fact that the threaded connection of the spark plug and the cylinder head (cylinder head) loses its tightness over time, so even if the spark plug works normally at low and medium loads, then at high pressure in the combustion chambers gives misfiring. Also see the replacement of spark plugs on Lada Priora, Kalina and Grant cars or.

The replacement of spark plugs must begin by removing the "-" terminal from battery. In order not to confuse the order of the high-voltage wires in the future, it is necessary to remove the protective cap only from the spark plug that you are changing at the moment.

Removing the protective cap from the candle

it is necessary to unscrew it either with a standard candle key or with a “21” head.

After you have unscrewed the candle, you need to check the gap between its electrodes using a special tool. For cars VAZ 2108, VAZ 2109, VAZ 21099 with carburetor engine modifications, the spark plug gap should be 0.7-0.85 mm, and for cars VAZ 2108, VAZ 2109, VAZ 21099, VAZ 2113, VAZ 2114 and VAZ 2115 with injection engine modifications, the spark plug gap should be 1.00-1.13 mm.

If the gap differs from the above, it is necessary to adjust it by bending the side electrode of the spark plug.

Having screwed in a new candle until it stops, it is necessary to tighten it with force, but not excessive. This is within a quarter of a turn after the spark plug touches the cylinder head. In case of excessive force, there is a risk of stripping the threads in the head of the block, which entails its repair.

Having installed the protective cap on the spark plug, we repeat the operation with the remaining candles in the same sequence.

There are 3 most common myths about spark plugs: when, how often and how often you need to change spark plugs.

Heed our advice and save on fuel consumption and new spark plugs.

Myth #1 Spark plug life

Most people and car owners assume that spark plug life is set by the manufacturer. And he can set both 30, 40, and even all 70 thousand km. run.

The reality of this problem is this: A normal factory spark plug should run 30,000 miles. But this does not apply to fake spark plug kits, which are now in abundance on the market. A fake can serve you as much as 5 thousand, or it may not work at all.

Myth #2 Fuel consumption

Many people think that while the car is driving, you can not change the candles and save money on this.

In reality, the picture of this situation is slightly different: if your spark plugs have already worked 30,000 km (or even 10,000 km, depending on the brand), then it is recommended to replace the spark plugs with new ones in order to avoid overspending gasoline (). So the picture in financial terms is as follows: it is much more profitable to save on fuel than on candles, because. the cost of candles is small compared to fuel.

Myth No. 3 Extending the life of candles

Logically, the quieter we drive, the longer the service life. In practice, things are a little different.

There is a concept called "self-cleaning spark plugs". This means that on high revs, the engine cleans the spark plug, which prolongs the service life. You also need to periodically check the gap in the spark plugs. It must meet the factory requirements of both the candle itself and your car. Therefore, always buy the right spark plugs. Do not flood spark plugs, especially in winter period- let the engine warm up, only then start driving.

So, let's sum up a little. How often to change spark plugs:

  1. From 20,000 km and above, if the candles are working properly.
  2. 10,000 km - if you want to save on fuel. In winter, you need to let the engine warm up, and from time to time you need to check the gaps on the candles. At the same time, do not forget to carry an additional set of candles with you, and then everything will be fine with you.

Welcome! Spark plugs - in all frets there are only four of them, in some cars high-voltage wires coming from the distributor (Carburetor cars) are connected to them, in some these wires are also connected to them, but coming from the ignition module (Injection 8 valve engines) and there are no high-voltage wires at all in some, and instead of them there is one ignition coil for each candle (These are 16 valve engines), usually there are difficulties with such engines, the owners sometimes have no idea at all about how to change the spark plugs in such an engine, but this is done very easily and in this article we will teach you how to do it in every engine that was installed on the Samara 2 family, and as you know, quite a few engines were installed on them, starting from an 8-valve carburetor and ending with a 16-valve engine with a distributed injection system (In other words, an injector).

Note! To carry out work on replacing spark plugs in the engine, you will need: Be sure to have a spark plug key (When you buy it, tell the seller for which engine you are buying the key, because at 16 valve engines, the candle wrench is completely different and of a different type), as well as a screwdriver, a wrench can also come in handy in order to throw off the minus terminal from the battery, thereby protecting yourself and the car from a short circuit!

Summary:

  • Replacing spark plugs
  • Additional video clip

Where are the spark plugs located? If you have an 8 valve engine, then the candles in them are located on the side of the cylinder block and they are screwed straight into the combustion chamber, see the second photo below for more details, in 16 valve engines everything is a little different, no wires, as we said to the candles it doesn’t work, you will immediately need to look for coils (All four coils are indicated by arrows in photo 1), under these coils there are spark plugs that are subject to replacement from time to time.

When should spark plugs be changed? It all depends on the operation of the engine, if the engine is very worn out or if the ignition is set incorrectly and detonation occurs from time to time, then in this case the candles are much more likely to be replaced, they are destroyed during detonation (What is detonation, read in the article: “Detonation occurring time from time to time in the car engine") and by the way it will not be possible to restore them, unlike if the engine works normally and without interruptions, just when everything works ideally, a plaque forms on the candles only from time to time, which can be removed by sandblasting and then candles will be like new, if you live in a big city, then look on the Internet, maybe someone is doing this for a very small price, sandblasting a candle will literally be like new and it can still be used in your car for a long time.

Note! The frequency of replacing candles is about 10-20 thousand km. If they are clogged, the car will obviously drive worse, and it will also be difficult to start in cold weather (the spark will be weak) and, most importantly, due to heavily worn candles, the car can generally get up and don’t go anywhere else, as a rule, this case is rare, you just change them in time and everything will be fine, but the fact that there is no spark on the candles, it may be due to various factors in which either the ignition system is to blame, or the module, or some one of the four coil!

8 Valve engines:

Everything is very simple on them, besides this, you can also see if there is a spark in the candle or not, which is very convenient when the car stalls, in general, let's start, we will immediately warn you which injection system does not matter at all (The injection system can be injection and carburetor on our cars) , everything is done the same way, first the minus terminal is removed from the battery (How to remove the terminal from the battery, read the article: “Replacing the battery in a car”), after this is done, disconnect one wire from the first candle (The wire is indicated by an arrow) and unscrew it , in its place, immediately screw another (New) and connect a wire to it and so go through all four candles, when they are changed, install the terminal on the battery and start the car, the engine should start the same way as before or even a little better and faster (Due to the fact that the spark passes better through the new electrodes of the candles), when it works extraneous sounds which should not have appeared before, everything should work clearly and without interruptions, except for this, in places where high-voltage wires cling to candles, there should not be a spark and in general the spark should not pierce the wires, otherwise install them better on candles or replace with new ones.

16 Valve engines:

Everything is very simple on them too, but there is one big minus, it will not be possible to see a spark and understand whether it is there or not, so if you take 8 valves, then everything is simple there, if the car does not start, any one candle is unscrewed and connected to it wire, after which the candle is brought to the mass and the car starts, thus you can immediately understand whether there is a spark or not, and you already know that the problem is in the ignition, on 16 valves, usually if it doesn’t start, you can sin a lot, on fuel system, for sensors, and so on, everything is checked in it using a computer and a diagnostic connector, so such cars are more sophisticated and, unlike carburetor ones, try to make a car yourself and sit down and drive, it’s unlikely to work out, let’s get back closer to the topic, replace the candles with 16 valve machines as follows, at the beginning exactly the same onboard network it is de-energized by dropping the minus terminal from the battery, then the bolt is unscrewed (The bolt for fixing one coil is indicated by an arrow for clarity and the outermost coil is indicated by a blue arrow, otherwise it is hard to see in the photo) securing one of any coils and the coil is removed from the hole in which it is located, when it is taken out, a special spark plug key for 16 valve machines is taken and the spark plug is turned out with it (see small photo) and it is also removed from the hole, replaced with a new one and a new one in reverse order, while installing the coil on it, too, do not forget, the other three spark plugs, go through in the same way.

Note! On 16 valve machines, which is on the prior, on the Samara 2 family, there is a screen on the cylinder head cover, you will need to remove this screen, otherwise you simply won’t get to the candles, how to remove it, read in the article: “Replacing the engine screen with Priore!

Additional video clip: For clarity, you can see the process of replacing spark plugs in two videos, the first video shows the process of replacing on 8 valve cars, and in the second on 16 valve cars, our advice to you, check out both, because this operation is very easy and know how it should be carried out by absolutely everyone.

Issue price

Quality products always cost more. Domestic products are several times cheaper, but the quality leaves much to be desired. Therefore, it is worth buying imported candles that will last much longer than domestic ones. At the same time, the life of the engine will be extended and fuel consumption will be more economical.

Video "Which spark plugs are better"

This video talks about SZ: device, types, which are better (the author of the video is VybratAuto - Automotive information site)

Timely replacement of the spark plug is the key to stable, long engine operation.

Briefly about the essence of the work of spark plugs

A spark plug is an ignition element designed to create a spark that ignites the combustible mixture under the cylinder piston. Their number is determined by the number of cylinders in the engine block.

They are a nickel case with a ceramic insulator, inside which a contact rod passes. Their synchronous operation is achieved by replacing the entire set, that is, 4 pieces. It is desirable that they be of the same brand and manufacturer.

Replacement time

The failure of the candle occurs due to improper operation of the car, incorrect selection of their brand, bad fuel. As a result, defects appear on the elements, by which it is possible to identify an engine malfunction.

Main malfunctions

  1. The body of the candle, the electrode are oily . Occurs due to wear of piston removable rings. The oil between the rings and the cylinder wall penetrates into the combustion chamber, flooding the electrode. A wet element does not spark regularly, and the engine starts to run intermittently, with a drop in power. There is a need to repair the motor with all the ensuing problems.
  2. Chip or breakage of the insulator . This defect, in order to avoid detonation, requires the replacement of candles.
  3. Plaque on the hull (prevents sparks). Requires thorough cleaning. The reason for the appearance of plaque is considered to be the low quality of fuel (gasoline).
  4. Chassis overheating (presence on it white shade). The motive for this is high-octane gasoline, for example, AI 95 instead of AI76 or AI 92. On the VAZ-2114, owners recommend pouring 92 gasoline.
  5. Spark plug brand mismatch to the engine also causes them to overheat.

The white color of the insulator, the melted electrode indicate the use of a lean combustible mixture. This leads to the appearance of carbon deposits inside the cylinder. And the excessive length of the threaded element of the candle leads to damage to the piston.

Spark plug replacement process

So, a candle replacement is available to any owner with a candle wrench, a metal brush, compressed air (preferably from a tire pump), a set of new candles. To do this, turn off the engine, allowing it to cool.

To avoid damage to the threaded socket of the block head, the spark plug is turned out after the engine has cooled down.


If the engine is running intermittently, the candles are checked for defects. Identification of such is carried out by alternately disconnecting the wires. It must be remembered that when removing the wire from a suspicious (defective) candle, there are no changes in the operation of the motor by ear.

When to change

Even with high-quality ignition of the mixture, engine stability, candles should be changed in a timely manner. You need to do this from the appearance of his non-rhythmic work.

Proper operation of the car will provide 30, and sometimes 40 thousand kilometers on one set.

Replacing a candle is connected:

  • Bad engine start.
  • An increase in gasoline consumption.
  • Power reduction.
  • Motor troit.
  • Long mileage without changing spark plugs.

To increase the service life, it is necessary to regularly check the gap between the electrodes. The operation of a car with an unheated engine, especially in winter, negatively affects the operation of spark plugs.

Gap of spark plugs on VAZ-2114

The wear of the electrodes negatively affects the internal combustion engine and this can be determined by increased fuel consumption. Fuel consumption on the VAZ-2114 in urban operation should not exceed 10 liters.

So, large gap is better for ignition , since a larger volume of the combustible mixture passes into the contact interval and its high-quality ignition occurs. But such a situation can lead to a spark break, especially when the engine is running at high speeds.

A small gap results in a powerful but short spark , whose arc may not break. The situation is fraught with the fact that fire plasma remains between the contacts. And this leads to the failure of the short circuit (ignition coil) and long-term downtime of the car.

When installing candles, it is useful to visually check the SZ for possible curvature of the electrode or changes in other parameters during their delivery to the place.

When purchasing SP in a store, setting these parameters is not required. The choice must be made based on the brand of your vehicle.

The period for replacing spark plugs comes every 30 thousand km. Old spark plugs can lead to increased fuel consumption.

Regularly check the reliability of the connections of high-voltage wires with candles, coil and ignition distributor. Wipe high voltage wires as they become dirty. Dirt can cause current leakage.

Important
Check and change spark plugs on a cold engine.
Do not tighten the spark plugs very tightly, the ceramic insulator may be damaged by this and the operation of the spark plug, and as a result, the engine, will be disrupted.

  • The engine starts to start badly
  • Increased fuel consumption
  • Sometimes, the engine tunes
  • Decreased vehicle dynamics
  • Long mileage without changing spark plugs

According to the condition of the candles, you can diagnose the engine, but more on that below.

Replacing spark plugs

Spark plugs on the engine VAZ 2110 2114 8 valves are located in the front wall of the engine.

1. Remove the wire from the “-” terminal of the battery

2. When removing the tip from the spark plug, do not pull on the wires. Stay as shown in the photo. If you need to remove all the tips, first mark the high voltage wires. Each wire belongs to a specific cylinder.

3. Wipe the candle niches. (Dirt can get through the spark plug hole into the block)

4. Carefully unscrew the candle with a special (candle or suitable head on “21”) wrench. If the spark plug does not budge due to soot, spray WD-40 into the threaded hole to avoid damaging the threads.

Engine diagnostics by spark plugs

When there is a crack on the insulator, there is damage to the thread or electrode, the candle must be replaced.

Light brown soot means that the spark plug is working properly, just like the engine.

Lack of soot on the candle:

  • engine running lean
  • ignition timing incorrectly set
  • spark plug brand mismatch with engine type.

Shiny black soot means that oil is getting into the cylinder. Such candles need to be changed or at least cleaned, and also look for the cause of oil getting into the cylinder
